Overview

Synchronous Buck Controller for Dynamic Load-Voltage Applications POWER MANAGEMENT Description The SC470 is a single output, constant on-time synchronous-buck, pseudo-fixed frequency, PWM controller intended for use in notebook computers and other battery operated portable devices.
Features include high efficiency and fast dynamic response with no minimum on-time.
The excellent transient response means that SC470 based solutions will require less output capacitance than competing fixed frequency converters.
